What is the lowest gain for OPA541AP that the chip still stable operate?

I decide to add 6SN7 SRPP buffer in front of it to solve the gain problem OPA541 but the 14X Gain of the buffer seem to make too high gain when using with 10X power amp.

So can the OPA541AP operate stable with the gain of 3-4 X?
